the last carousel you'll ever need



To start working with Slick right away, there's a couple of CDN choices availabile to serve the files as close, and fast as possible to your users:

Example using jsDelivr

Just add a link to the css file in your <head>:

<link rel="stylesheet" type="text/css" href="//"/>
<!-- Add the slick-theme.css if you want default styling -->
<link rel="stylesheet" type="text/css" href="//"/>

Then, before your closing <body> tag add:

<script type="text/javascript" src="//"></script>

Package Managers

# Bower
bower install --save slick-carousel

npm install slick-carousel

Data Attribute Settings

In slick 1.5 you can now add settings using the data-slick attribute. You still need to call $(element).slick() to initialize slick on the element.


<div data-slick='{"slidesToShow": 4, "slidesToScroll": 4}'>


Option Type Default Description
accessibility boolean true Enables tabbing and arrow key navigation
adaptiveHeight boolean false Adapts slider height to the current slide
autoplay boolean false Enables auto play of slides
autoplaySpeed int 3000 Auto play change interval
centerMode boolean false Enables centered view with partial prev/next slides. Use with odd numbered slidesToShow counts.
centerPadding string '50px' Side padding when in center mode. (px or %)
cssEase string 'ease' CSS3 easing
customPaging function n/a Custom paging templates. See source for use example.
dots boolean false Current slide indicator dots
dotsClass string 'slick-dots' Class for slide indicator dots container
draggable boolean true Enables desktop dragging
easing string 'linear' animate() fallback easing
edgeFriction integer 0.15 Resistance when swiping edges of non-infinite carousels
fade boolean false Enables fade
arrows boolean true Enable Next/Prev arrows
appendArrows string $(element) Change where the navigation arrows are attached (Selector, htmlString, Array, Element, jQuery object)
appendDots string $(element) Change where the navigation dots are attached (Selector, htmlString, Array, Element, jQuery object)
mobileFirst boolean false Responsive settings use mobile first calculation
prevArrow string (html | jQuery selector) | object (DOM node | jQuery object) <button type="button" class="slick-prev">Previous</button> Allows you to select a node or customize the HTML for the "Previous" arrow.
nextArrow string (html | jQuery selector) | object (DOM node | jQuery object) <button type="button" class="slick-next">Next</button> Allows you to select a node or customize the HTML for the "Next" arrow.
infinite boolean true Infinite looping
initialSlide integer 0 Slide to start on
lazyLoad string 'ondemand' Accepts 'ondemand' or 'progressive' for lazy load technique. 'ondemand' will load the image as soon as you slide to it, 'progressive' loads one image after the other when the page loads.
pauseOnFocus boolean true Pauses autoplay when slider is focussed
pauseOnHover boolean true Pauses autoplay on hover
pauseOnDotsHover boolean false Pauses autoplay when a dot is hovered
respondTo string 'window' Width that responsive object responds to. Can be 'window', 'slider' or 'min' (the smaller of the two).
responsive array null Array of objects containing breakpoints and settings objects (see example). Enables settings at given breakpoint. Set settings to "unslick" instead of an object to disable slick at a given breakpoint.
rows int 1 Setting this to more than 1 initializes grid mode. Use slidesPerRow to set how many slides should be in each row.
slide string '' Slide element query
slidesPerRow int 1 With grid mode initialized via the rows option, this sets how many slides are in each grid row.
slidesToShow int 1 # of slides to show at a time
slidesToScroll int 1 # of slides to scroll at a time
speed int 300 Transition speed
swipe boolean true Enables touch swipe
swipeToSlide boolean false Swipe to slide irrespective of slidesToScroll
touchMove boolean true Enables slide moving with touch
touchThreshold int 5 To advance slides, the user must swipe a length of (1/touchThreshold) * the width of the slider.
useCSS boolean true Enable/Disable CSS Transitions
useTransform boolean true Enable/Disable CSS Transforms
variableWidth boolean false Disables automatic slide width calculation
vertical boolean false Vertical slide direction
verticalSwiping boolean false Changes swipe direction to vertical
rtl boolean false Change the slider's direction to become right-to-left
waitForAnimate boolean true Ignores requests to advance the slide while animating
zIndex number 1000 Set the zIndex values for slides, useful for IE9 and lower
Responsive Option Example

The responsive option, and value, is quite unique and powerful. You can use it like so:


  // normal options...
  infinite: false,

  // the magic
  responsive: [{

      breakpoint: 1024,
      settings: {
        slidesToShow: 3,
        infinite: true

    }, {

      breakpoint: 600,
      settings: {
        slidesToShow: 2,
        dots: true

    }, {

      breakpoint: 300,
      settings: "unslick" // destroys slick



In slick 1.4, callback methods were deprecated and replaced with events. Use them before the initialization of slick as shown below:

// On swipe event
$('.your-element').on('swipe', function(event, slick, direction){
  // left

// On edge hit
$('.your-element').on('edge', function(event, slick, direction){
  console.log('edge was hit')

// On before slide change
$('.your-element').on('beforeChange', function(event, slick, currentSlide, nextSlide){
Event Params Description
afterChange event, slick, currentSlide After slide change callback
beforeChange event, slick, currentSlide, nextSlide Before slide change callback
breakpoint event, slick, breakpoint Fires after a breakpoint is hit
destroy event, slick When slider is destroyed, or unslicked.
edge event, slick, direction Fires when an edge is overscrolled in non-infinite mode.
init event, slick When Slick initializes for the first time callback. Note that this event should be defined before initializing the slider.
reInit event, slick Every time Slick (re-)initializes callback
setPosition event, slick Every time Slick recalculates position
swipe event, slick, direction Fires after swipe/drag
lazyLoaded event, slick, image, imageSource Fires after image loads lazily
lazyLoadError event, slick, image, imageSource Fires after image fails to load


Methods are called on slick instances through the slick method itself in version 1.4, see below:

// Add a slide

// Get the current slide
var currentSlide = $('.your-element').slick('slickCurrentSlide');

This new syntax allows you to call any internal slick method as well:

// Manually refresh positioning of slick
Method Argument Description
slick options : object Initializes Slick
unslick Destroys Slick
slickNext Triggers next slide
slickPrev Triggers previous slide
slickPause Pause Autoplay
slickPlay Start Autoplay (will also set autoplay option to true)
slickGoTo index : int, dontAnimate : bool Goes to slide by index, skipping animation if second parameter is set to true
slickCurrentSlide Returns the current slide index
slickAdd element : html or DOM object, index: int, addBefore: bool Add a slide. If an index is provided, will add at that index, or before if addBefore is set. If no index is provided, add to the end or to the beginning if addBefore is set. Accepts HTML String
slickRemove index: int, removeBefore: bool Remove slide by index. If removeBefore is set true, remove slide preceding index, or the first slide if no index is specified. If removeBefore is set to false, remove the slide following index, or the last slide if no index is set.
slickFilter filter : selector or function Filters slides using jQuery .filter syntax
slickUnfilter Removes applied filter
slickGetOption option : string(option name) Gets an option value.
slickSetOption change an option, refresh is always boolean and will update UI changes...
option, value, refresh change a single option to given value; refresh is optional.
"responsive", [{ breakpoint: n, settings: {} }, ... ], refresh change or add whole sets of responsive options
{ option: value, option: value, ... }, refresh change multiple options to corresponding values.


Initialize with:

  dots: true,
  speed: 500

Change the speed with:

$(element).slick('slickSetOption', 'speed', 5000, true);

Destroy with:
